<p>The <code class="literal">simple</code> analyzer breaks text into terms whenever it encounters a
character which is not a letter. All terms are lower cased.</p>

<div class="console_widget" data-snippet="snippets/851.console"></div>
<p>The above sentence would produce the following terms:</p>

<p>The <code class="literal">simple</code> analzyer consists of:</p>
<div class="variablelist">
<dl class="variablelist">
<dt>
<span class="term">
Tokenizer
</span>
</dt>
<dd>
<div class="ulist itemizedlist">
<ul class="itemizedlist">
<li class="listitem">
<a class="xref" href="analysis-lowercase-tokenizer.html" title="Lowercase Tokenizer">Lower Case Tokenizer</a>
</li>
</ul>
</div>
</dd>
</dl>
</div>
<p>If you need to customize the <code class="literal">simple</code> analyzer then you need to recreate
it as a <code class="literal">custom</code> analyzer and modify it, usually by adding token filters.
This would recreate the built-in <code class="literal">simple</code> analyzer and you can use it as
a starting point for further customization:</p>

<pre class="programlisting prettyprint lang-console">PUT /simple_example
